Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.

Paraphin [41]

Answer:

Step-by-step explanation:

For a quadratic equation ax² +bx +c= 0, the quadratic formula is as below:

$\boxed{x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} }$

x² -12x +7= 0

$x = \frac{ - ( - 12)± \sqrt{( - 12) {}^{2} - 4(1)(7) } }{2(1)}$

$x = \frac{12± \sqrt{144 - 28} }{2}$

$x = \frac{12± \sqrt{116} }{2}$

$x = \frac{12± \sqrt{4(29)} }{2}$

$x = \frac{12±( \sqrt{4})( \sqrt{29} )}{2}$

$x = \frac{12±2 \sqrt{29} }{2}$

$x = 6± \sqrt{29}$

$∴x = 6 + \sqrt{29} \: \: \: or \: \: \:x = 6 - \sqrt{29}$

Given the speeds of each runner below, determine who runs the fastest.

alexandr402 [8]

Answer:

Brooke

Step-by-step explanation:

We can solve this by figuring out how far each person runs a second

Stephanie runs 12 feet a second so nothing needs to be done here

Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet

Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75

Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18

Brooke obviously runs the furthest in one second and therefore she's the fastest runner
